TANK.

Specification of Letters Patent:

Patented March 3, 1908.

Application filedApril 19. 1906- Serial No. 312.694.

To all whom it may concern: Be it known that I, FRANK B. WENT- WORTH, acitizen of the United States, and

resident of Independence, county of Montgomery, and State of Kansas,have invented certain new and useful Improvements in Tanks, of which thefollowing is a specification, and which are illustrated in theaccompanying drawings forming a part thereof.

The invention relates to tanks of sheet 'metal, and particularly tothose which are of generally cylindrical shape and have walls composedof a plurality of sections.

- The invention has for its object to provide simple and eflicient meansfor uniting the several sections of the walls of the tank of the kinddescribed, and to increase the strength and stiffness of such tanks,thereby rendering them less likely to become indented or misshapen-byrough handling or. in transportation from place to place:

The invention -is exemplified in the structure hereinafter described andillustrated in invention; and Figs. 2, 3 and 4 are sectional theaccompanying drawings, in which Flgure 1 Ban elevation, partly insection, of'a tank constructed in accordance withthe details of-the samedrawn to a larger scale.

The invention is applicable tosheet metal tanks of various forms.

In the drawings is shown acistern for the storage of liquids which, inpractice, Will usually be of moderate size. Its walls are preferabl ironand ormed in sections, 10, 11, 1'2, 13 and 14, one of these sections, as10, being of the proper shape'to provide a bottom for the tank, whileanother, as 14, may form a domeshaped or conical top having a fillingopening 15. The remaining sections, 11, 12 and 13, as shown, arecylindrical in form and compose the body wall of the tank.

In carrying out the invention there is provided a plurality of metalbands or hoops 16 of channel section, each preferably having its flanges17, 18, directed outwardly. These hoops are most conveniently formed bybending a strip of channel iron to a circle and uniting the ends in anyconvenient manner, as by means of a tie plate 25 and rivets 26.Preferably the hoops 16 are of-galvanized material and one of them isemployed for nection.

of a heavy grade of galvanized uniting each of the sections of the tankwith the next adjacent section. In forming this connection the hoopmember is, as shown, placed within the tank and the meeting edges of thetank sections are flanged inwardly, as indicatedat 1 9, 20, Figs. 3 and4" of the drawings, the flanges being then fitted into the groove of thehoop member '16 and boundin position by means of a band 21 preferably ofround iron" or stout wire; If desired the joints thus formed may besweated or calked with solder. As shown a liberal amount of solderingmaterial 22 is applied about the binding member 21,

to give thejoint a smooth or finished a pearance, while some of thissolder issoa ed 0r sweated intov the joint to unite the flanged edges19, 20, of the tank sections with'the web of the hoop member 16,as'indicated at 23, thus forming a perfectly water-tight oonr' In theform of tank shown in the drawing, the rim of the filling opening 15isstrengtherred bya tubular hoop 24, to which the edges of the uppersection 14 of the tank are fitted and united by screw-bolts 27.

By the improvement herein shown and described, there is provided a sheetmetal tank of great dur ability and strength, as the hoop memberslfiserve not only as a convenient means for uniting the several sections ofthe tank but, also effectively resist various forms of rough usage towhich it may be' subjected and which might otherwise seriously distortorpuncture its walls.

I claim as my invention In a tank having sectional walls of sheet metalin combination, a circumferential hoop of channel section having itsflanges directed outwardly, contiguous edges of adjacent wall sectionsof the tank bein flanged inwardly and laid in the groove of t e channel, a band surrounding the tank and bearing upon the edges of the wallsections within the groove, and a calking of solder for the joint thusformed, the solder being applied over the band. i I
